Abstract

This learning module introduces nanoHUB users to the CNTbands simulator. A brief introduction to CNTbands is presented, followed by voiced presentations featuring the simulator in action. Upon completion of this module, users should be able to use this simulator to gain valuable insight into the electronic and physical properties of cutting edge devices.

This series is a set of materials formerly known as a "Learning Module." It has been converted into an Online Presentation.  Please feel free to pause the presentation at anytime so you can try the different exercises with the simulation tool.
